Most of the members of the Capetian dynasty bore a version of the arms of France. The arms of France were adopted by the Capetian kings only in the twelfth century. Consequently, the cadet branches that had branched off in earlier periods (Burgundy, Vermandois, Dreux and Courtenay) bore entirely different arms.
Today, many coat of arms of places in France are derived from the royal arms of the French king.

The arms of France was first used by Philip Augustus at the beginning of the age of heraldry.
